Step 1
Price elasticity of demand
- It is an indicator of how price-sensitive the quantity needed is.
- For practically every good, demand declines as the price rises, but more so for some goods than others.
- When a price increases by 1% while all other factors remain constant, the price elasticity provides the percentage change in the quantity required.
- If the elasticity is 2, a 1% increase in price results in a 2% decrease in the amount demanded.
- Other elasticities quantify the relationship between the quantity sought and other factors, such as the demand elasticity based on income.
